Abstract
An object of the present invention is to search a new medicinal use of 5-[p-[2-(methyl-2-pyridylamino) ethoxy]benzyl]-2,4-thiazolidinedione and 5-[[4-[2-(5-ethyl-2-pyridinyl)ethoxy]phenyl]methyl]-2,4-thiazolidinedione. 5-[p-[2-(methyl-2-pyridylamino)ethoxy]benzyl]-2,4-thiazolidinedione, 5-[[4-[2-(5-ethyl-2-pyridinyl)ethoxy]phenyl]methyl]-2,4-thiazolidinedione or a salt thereof exerts an excellent improving effect on corneal disorder models, therefore, it is useful as a therapeutic agent for a keratoconjunctival disorder such as dry eyes, corneal ulcer, keratitis or conjunctivitis.
Description
[0001] This application is a continuation-in-part application of International Application PCT / JP2005 / 008584 (not published in English) filed May 11, 2005.TECHNICAL FIELD [0002] The present invention relates to a therapeutic agent for a keratoconjunctival disorder such as dry eyes, corneal ulcer, keratitis or conjunctivitis, comprising as an active ingredient, 5-[p-[2-(methyl-2-pyridylamino)ethoxy]benzyl]-2,4-thiazolidinedione, 5-[[4-[2-(5-ethyl-2-pyridinyl)ethoxy]phenyl]methyl]-2,4-thiazolidinedione, both of which are a thiazolidinedione derivative, or a salt thereof. BACKGROUND ART [0003] Cornea is a transparent avascular tissue having a diameter of about 1 cm and a thickness of about 1 mm, while conjunctiva is a mucosal membrane covering the eyeball surface posterior to the corneal margin, and the back face of the eyelid. The cornea and the conjunctiva are known to significantly affect the visual function. Keratoconjunctival disorders caused due to a variety of diseases such as c...
